Spy on insertMany calls

[cristian-moreno-ruiz]

I want to spy on a call to insertMany, but I can't seem to find the proper way to do it. I currently do something similar for find and it seems to work fine. This is how my test looks like:

const findSpy = jest.fn().mockResolvedValue([]);
const insertManySpy = jest.fn();
mockingoose(accountModel).toReturn(findSpy, 'find');
mockingoose(accountModel).toReturn(insertManySpy, 'insertMany');

I can manage to access the conditions of the find queries like this findSpy.mock.calls[0][0]._conditions.

However, I've not been able to check through the documents to be inserted using the insertManySpy. Anyone knows how can I do this?
